Which hierarchy of controls level is considered most effective for eliminating workplace hazards?
Answer: Elimination
Elimination physically removes the hazard from the workplace and is the most effective level in the hierarchy of controls.
Under OSHA's Hazard Communication Standard (HazCom), Safety Data Sheets must contain how many sections?
Answer: 16
OSHA's HazCom Standard (29 CFR 1910.1200) requires Safety Data Sheets to follow a standardized 16-section format aligned with the GHS.
A worker is exposed to a chemical with a TWA-PEL of 50 ppm. Air monitoring shows an 8-hour average of 65 ppm. What is the most appropriate immediate action?
Answer: Issue respirators and investigate root cause
Exceeding the PEL requires immediate interim protection (respirators) while investigating the root cause and implementing engineering controls.
What term describes the concentration of an airborne contaminant that is immediately dangerous to life or health (IDLH)?
Answer: The level at which escape without irreversible harm is no longer possible
IDLH is defined as the concentration that poses immediate threat to life or causes irreversible health effects that impair ability to escape.
Which type of ventilation system is preferred for controlling airborne contaminants at their point of generation?
Answer: Local exhaust ventilation (LEV)
Local exhaust ventilation captures contaminants at the source before they disperse into the work environment, making it more effective than dilution ventilation.
Under OSHA's Bloodborne Pathogens Standard, which practice is the PRIMARY method for preventing occupational exposure to HIV and HBV?
Answer: Universal Precautions
Universal Precautions treat all human blood and certain body fluids as if infectious, forming the primary prevention strategy under 29 CFR 1910.1030.
A safety practitioner is evaluating noise levels in a manufacturing facility. Which instrument should be used to measure a worker's actual personal noise dose over a full shift?
Answer: Noise dosimeter
A noise dosimeter is worn by the worker and integrates exposure over the entire shift, providing an accurate personal dose measurement.
